BOLSTER-SPRING oe VEHICLES.

SPECIFICATION forming part of Letters Patent No.37 6,857, dated January24, 1888.

Application filed June 15, 1887.

To aZZ whom it may concern.-

Be it known that I, EDWARD CLIFF, of Oswego, in the county of Oswego, inthe State of New York, have invented new and useful Imthe same andreduces the cost of the manufacture thereof, and at the same time formsa secure, durable, and efficient spring-support for the vehicle-body;andthe invention also consists in novel means-of bracing the bodysupportingbar at the ends as well as at the center, all as hereinafter more fullydescribed, and specifically set forth in the claims.

- In, the annexed drawings, Figure l is a top plan view of one of theend portions of the vehicle-body spring-support embodying myimprovements.

Fig. 2 is a front elevation of the same. Fig. 3 is a verticallongitudinal section through the center of the aforesaid parts. Fig. 4.is an inverted plan view of the spring and its attachment. Fig. 5 is anend View of a bolster with my improved spring mounted thereon. Fig. 6 isa transverse section on line mac, Fig. 4; and Fig. 7 is a detachedperspective view of the shoe by which the spring is connected with thebolster.

Similar letters of reference indicate corresponding parts.

B represents the bolster of a wagon, and 0 one of the stakes, secured tothe ends of the bolster in the usual manner.

D denotes the body-supporting bar, which is arranged over the bolsterparallel therewith and is guided on the stakes G. The bar D, I supportupon the bolster at each end by two coil-springs, a a, arranged axiallyvertically at opposite sides of the bolster, and formed directly attheir bases with bearings on the bolster and with short paralleloutward-projecting shanks b b, which are separated from each other, soas to embrace between them the nlent of the spring to, the bar D.

site sides of said notch for the receptionof the ends of the shanks b b.The portions of the bases of the coils adjacent to the shanks rest ontheinner end of the shoe, which is prefer ably formed flaring for thatpurpose. The two coilsa a are united at the top by an elongated .6

. 5, directions from the shanks b b and lengthwise loop, Z, extendingfrom said coils in opposite the bar D. Said loop I spread apart to forman opening between its inner sides extendmg under side of the bar D bymeans of plates d d, entering the opening in the loop and attached tothe aforesaid barby bolts passing through the plates and bar, saidplates being formed with grooves f f on their adjacent sides, whichgrooves inclose the-attaching-loop Z, so as to confine the same to theaforesaid plates. By

which they the length of'the loop, and I secure it to the I W spreadingthe loop Z, as aforesaid, I obtain a' f broad bearing and better holdfor the attach- The plate d, I form with a guide, g, by which it slideson the stake G. The body-supporting bar D, I brace by means of a strap,h, ex-

tending lengthwise of the under side of said bar and clamped at its endsbetween the bar D, underlying plates d 11 at opposite ends of theaforesaid bar, and between the'central.

portion of the bar and strap I interpose a strut, 15, said strap andstrut forming a'truss which, together with the elongated plates d (1,

serves to brace the bar D at the centeras well as at its ends.

I do not claim, broadly, a vehicle-spring composed of two vertical coilsformed withat-' taching-shanks'at their upper and lower ends, as I amaware that the same is not new; but

c What I do claim as new, and desire to secure by Letters Patent,is-- 1. In combination with the bolster B, stake O, and the bar D,arranged over the bolster parallel therewith'and guided on the stake,'asshown, the coils a a, arranged axially vertically at opposite sides ofthe bolster and unitedat i the shanks b b,extending from the base of thecoils and resting upon the bolster and terminatingat opposite sides ofthe stake, substantially as described and shown.

, 2. In combination with the bolster B, stake G, and bar D over saidbolster and parallel therewith, the axially-vertical coils a a atopposite sides of the bolster,united at the top by the elongated loop Z,formed with an opening throughout its length, the shanks b I), extendingfrom the base of the coils and resting 011 the bolster and terminatingat opposite sides of the stake, plates entering the opening of the loop,and bolts securing said plates to the bar D, substantially as set forth.

3. In combination with the bolster B and bar D. over the bolster andparallel therewith, the axiallyvertical coils a a, united at the top bya loop formed integral therewith and formed at their base with bearingson the bolster directly under the coils, substantially as set forth.

4. The combination, with the bolster B,stake G, and bodysupporting barD, of the coils a (1, arranged axially vertically at opposite sides ofthe bolster and united by the loop Z, formed in one piece with saidcoils and extending lengthwise the bar D, and the shanksb b, supportedupon the bolster and separated'and embracing the base of the stakebetween them, substantially as described and shown.

5. In combination with the bolster B, stake G, bar D, and the coils a a,terminating with the attachingshanks b b, the shoe 0, secured to thebolster and formed with the notch n and with the grooves e e, forsupporting the attachingshanks b b of the coils, substantially asdescribed and shown.

6. In combination with the bolster B, bar

D, and the coils a a, formed in one piece with the elongatedattaching-loop Z, the platesd and d, secured to the bar D and providedin their adjacent sides with the grooves ff, inclosing the loop Z,substantially as described and shown.

7. In combination with the bolster 13, stake 0, bar D, and the coils aa, united by the elongated loop Z, the plate d, secured to the underside of said bar and formed with the vertical guide 9 and with thegroove f, and

the plate d, secured to the under side of the plate at and provided witha corresponding groove,f,substantially as described and shown.

8. The combination, with the barD and its supporting-springs a a, ofplates (Z 01, secured to .the under side of opposite ends of said bar,

the strap h, clamped at its ends between the bar D and plates (Z d, andthe strut t, interposed between the said bar and strap, substantially asdescribed and shown.

In testimony whereof I have hereunto signed my name and affixed my seal,in the presence of two attesting witnesses, at Syracuse, in the countyof Onondaga, in the State of New York, this 2d day of June, 1887.
